Even more peripherals, such as four serial audio interfaces (SAI) with SPDIF output support, three full-duplex I²S interfaces, a SPDIF input interface supporting four inputs, two USB OTG with dedicated power supply and Dual-mode Quad-SPI interface, two FD-CAN controllers, a high-resolution timer, a TFT-LCD controller, a JPEG codec, two SDIO interfaces and many other analog peripherals including three fast 16-bit ADCs, two comparators and two operational amplifiers.

1 Mbyte of SRAM with a scattered architecture:

192 Kbytes of TCM RAM (including 64 Kbytes of ITCM RAM and 128 Kbytes of DTCM RAM for time-critical routines and data), 512 Kbytes, 288 Kbytes and 64 Kbytes of user SRAM, and 4 Kbytes of SRAM in backup domain to keep data in the lowest power modes

The multi-power domains architecture allows the different power domains to be set in low-power mode to optimize the power efficiency. In addition to the main regulator featuring voltage scaling to supply the core in different voltage ranges during Run and Stop modes, the device also embeds a USB regulator to supply the embedded physical layer (PHY) and a backup regulator.

STM32 step-by-step is a learning program, and is part of the STM32 Education initiative, designed for anyone interested in getting started on building projects with the STM32 microcontroller and its powerful ecosystem of development boards and software programming tools.
